Intake device with flap bearing arrangement and flap bearing arrangement

A flap shaft assembly, comprising:

• an elongated flap shaft, wherein a direction of elongation of the flap shaft defines an axial direction;
• a plurality of flap bearing arrangements, each including:
• two side parts, the two side parts spaced apart from each other;
• a hollow tube section extending between and connecting the two side parts, the tube section extending in the axial direction;
• an O-ring, formed as an annular ring of an elastomer, circumferentially surrounding the tube section, the O-ring arranged between the two side parts;
• wherein the two side parts each have a substantially rectangular cross-section perpendicular to the hollow tube section extending between and connecting the two side parts;
• wherein the two side parts each have a radially outer circumference, where radial relative to the tube section connecting the two side parts;
• and
• wherein in a circumferential direction around the annular ring of the O-ring, some radially outer circumferential sections of the O-ring project outwardly beyond the radially outer circumference of the of the side parts, while other radially outer circumferential sections of the O-ring do not project radially outwardly beyond the radially outer circumference of the of the side parts;
• and
• wherein each of the two side parts has:
• a cylinder support formed as a hollow cylinder, formed at and lying against an axially outer surface of the side part and concentric with the hollow tube section;
• wherein the hollow tube section is a single continuous hollow tube which extends continuously through both of the two side parts and through their cylinder supports and through the O-ring;
• and
• wherein each of the plurality of flap bearing arrangements are spaced apart axially on the elongated flap shaft.
